Problems solved by technology
At present, the displacement table is often used in precision machining. There are many defects in the existing displacement table. For example, the positioning accuracy is not enough, and whether the equipment is placed perpendicular to the ground cannot be detected, and the processing effect may be affected by the inclination. It is impossible to detect the components during the processing, resulting in poor processing effect and unable to detect the displacement of parts in real time

The invention discloses a precision displacement worktable and relates to the field of micro-displacement equipment. The precision displacement worktable can achieve precise positioning in an XY plane. A tool bottom plate is arranged on the X-axis, a U-shaped supporting plate is installed on the bottom plate, a ball screw module, a servo motor, a grating ruler sensor and a bearing supporting seatare installed in the U-shaped supporting plate, two guide rods are installed on the bearing supporting seat, and a Y-axis mechanism can be prevented from deflecting in the moving process. A supportingplate is arranged on the Y axis, and the ball screw module, the servo motor, a worktable plate and the grating ruler sensor are installed on the supporting plate. By means of the precision displacement worktable, the servo motor drive the ball screw module to complete rough positioning, and a grating ruler detects displacement of the worktable and then micro-displacement adjustment is carried outto complete fine positioning.
Description
technical field [0001] The invention relates to the field of micro-displacement equipment, in particular to a precision displacement workbench Background technique [0002] Displacement workbench refers to the equipment that adjusts and controls the displacement, speed, acceleration, and other parameters of the workpiece by manual means. The displacement table device includes several parts such as transmission mechanism, control system, displacement detection system and other auxiliary equipment. It mainly includes motor, ball screw module, guide rod, grating sensor and controller. At present, the displacement table is often used in precision machining. There are many defects in the existing displacement table. For example, the positioning accuracy is not enough, and whether the equipment is placed perpendicular to the ground cannot be detected, and the processing effect may be affected by the inclination. It is impossible to detect the components during the processing, re...
